摘要
针对粒子群优化算法在方向图综合中如何评价其性能的问题,通过定义有效性和稳定性两个性能指标,从统计角度对粒子群算法在共形阵低副瓣方向图综合中的性能进行了评价.仿真结果表明所定义的性能指标可以有效评价算法综合方向图的性能,具有较强的实际应用指导意义.
Aiming at the performance of particle swarm optimization algorithm using in beam pattern synthesis, the algorithm when synthesizing low lobe-side beam pattern of conformal array antennas by defining the value of validity and stability in the view of statistical is analyzed. The results show that the two indexes thas can ana lyze the performance of algorithm, thus can guide the actual engineering effectively.
